What Is a Catalytic Converter Replacement?

The catalytic converter, part of your vehicle's exhaust system, uses chemical catalysts such as platinum, palladium, and rhodium to reduce the harmful emissions from your tailpipe. When it is damaged or no longer effective, it is removed and a new "cat" is installed in your exhaust system.

How Is a Catalytic Converter Replacement Done?

The exhaust pipe before and after the catalytic converter is cut and a new converter is welded into place or otherwise attached.

Symptoms That Indicate You Need a Catalytic Converter Replacement

A failed emissions test could indicate a problem with the catalytic converter, and a "rotten egg" smell is a common symptom as well. Rattling, reduced engine performance, and diminished fuel economy may also be signs of a problem with the converter, and a converter problem is one of the most common reasons for a "check engine" light.


A catalytic converter is legally required on most road vehicles and is necessary to pass the periodic emissions tests that many state governments require. Problems with the catalytic converter can also cause it to overheat, creating a fire hazard under the vehicle.

Average Cost

Costs vary widely, from $150 for parts and labor to $1,600 or more. Most of the cost is in the parts, only requiring about an hour of labor.

Can I Do It Myself?

Most home mechanics don't have the equipment needed to do a quick but complete job by cutting the pipes and welding the new catalytic converter into the exhaust line. Do-it-yourself bolt-on repair is possible, but it's a tough job performed in a tight spot.

Safety: Can I Drive Without Doing Catalytic Converter Replacement?

If the catalytic converter is overheating, it is very dangerous to drive the vehicle. Damage that produces leaks of exhaust fumes underneath the car is also a serious problem. Emissions problems by themselves are important, but they don't prevent the safe operation of the vehicle. Engine performance may be reduced until a replacement is done.
